Le bouton de chaque disposition linéaire créée dynamiquement ne fonctionne pas seul dans la dernière mise en page linéaire

      }); 
     } 
    } 

Lors de l'exécution, je crée une mise en page linéaire. Le nombre de mises en page linéaires créées est le nombre d'enregistrements dans la base de données. La disposition linéaire comporte deux zones de texte et deux boutons. Le problème auquel je suis confronté est que seul le bouton de la dernière disposition linéaire fonctionne. Les boutons de la disposition linéaire précédente ne fonctionnent pas.

Essayez d'utiliser le code ci-dessous ..

public class CustAdp extends ArrayAdapter<String> { 

    Cursor cursor_subCat; 

    public CustAdp(Context context, Cursor cursor_subcategory) { 
     super(context, id); 
     this.cursor_subCat = cursor_subcategory; 
     cursor_subCat.moveToFirst(); 
    } 

    public int getCount() { 
     // TODO Auto-generated method stub 
     return cursor_subCat.getCount(); 
    } 

    public String getItem(int position) { 
     // TODO Auto-generated method stub 
     cursor_subCat.moveToPosition(position); 
     return cursor_subCat.getString(cursor_subCat 
       .getColumnIndex("Sub_CatName")); 
    } 

    public long getItemId(int position) { 
     // TODO Auto-generated method stub 
     cursor_subCat.moveToPosition(position); 
     return cursor_subCat.getInt(cursor_subCat 
       .getColumnIndex("Sub_IdAuto")); 
    } 

    @Override 
    public void notifyDataSetChanged() { 
     // TODO Auto-generated method stub 
     super.notifyDataSetChanged(); 
     cursor_subCat.requery(); 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 

     convertView = getLayoutInflater().inflate(R.layout.customsubcat, 
       null); 
     ImageView iv_subcat = (ImageView) convertView 
       .findViewById(R.id.image_region1); 
     TextView tv_subcat = (TextView) convertView 
       .findViewById(R.id.txt_regionname1); 
     Button btn_subcat = (Button) convertView 
       .findViewById(R.id.button_delete_subcat); 

     cursor_subCat.moveToPosition(position); 
     try { 
      byte[] subimage = cursor_subCat.getBlob(cursor_subCat 
        .getColumnIndex("Sub_CatImage")); 
      Bitmap bm = BitmapFactory.decodeByteArray(subimage, 0, 
        subimage.length); 
      iv_subcat.setImageBitmap(bm); 
      tv_subcat.setText(cursor_subCat.getString(cursor_subCat 
        .getColumnIndex("Sub_CatName"))); 
      subcat_id = cursor_subCat.getLong(cursor_subCat 
        .getColumnIndex("Sub_IdAuto")); 
      btn_subcat.setId((int) subcat_id); 
      id = cursor_subCat.getInt(cursor_subCat 
        .getColumnIndex("Sub_MyReceipe")); 
      convertView.setId(position); 
     } catch (Exception e) { 
      // TODO: handle exception 
     } 



     btn_subcat.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       temp = v.getId(); 
       Cursor c_subcat = db_SubCategory 
         .getReceipeFromSubCategory(temp); 
       c_subcat.moveToFirst(); 

       if (c_subcat.getCount() == 0) { 
        data = false; 
        showDialog(0); 
       } else { 
        data = true; 
        showDialog(0); 
       } 

      } 
     }); 
     return convertView; 

    } 

    class ViewHolder { 
     TextView tv_subcat; 
     Button btn_subcat; 
     ImageView iv_subcat; 
    } 
} 

Apporter des modifications dans le code ci-dessus vos besoins ... espérons que cela vous aidera ..

Answer 2

Parce que mon ami, vous définissez le « onclicklistener "s aux vues sélectionnées par le" findViewById "(avant la boucle while), et donc uniquement la définition de l'écouteur à un ensemble de vue. Ce que vous voulez faire mettre le contenu de la "fonction()" dans la boucle, et changer les noms d'affichage de cette fonction pour le nom de vue qui sont dans la boucle while.

ex.

while(cur.moveToNext()){ 
    btnbuy=new Button(this); 
    btnbuy.setId(i); 
    btnbuy.setHeight(55); 
    btnbuy.setWidth(75); 
    btnbuy.setTextColor(Color.rgb(105, 160, 38)); 
    btnbuy.setBackgroundResource(R.drawable.buy_stock); 
    btnbuy.setOnClickListener(new View.OnClickListener(){ 
     public void onClick(View v) { 
      Log.d("button id : ",""+btnbuy.getId()); 
     } 
    }); 
    ... 
}
